rsync –avz ./mywebsite/ root@192.0.2.0:/var/www/html/

Troubleshooting Tips

• Permission Issues: Verify the necessary permissions on the Droplet’s destination directory. You may need to use sudo or adjust directory ownership.
• Connection Refused: Verify that SSH is running on your Droplet and that you’re using the correct IP address.
• Firewall Settings: Make sure your Droplet’s firewall allows SSH connections (port 22 by default).

Security Considerations

• Use SSH Keys: SSH keys are more secure than passwords and prevent brute-force attacks.
• Limit User Access: Use a non-root user for file transfers when possible.
• Secure File Permissions: After uploading, set appropriate file permissions to protect sensitive data.

Next Steps

• Automate Transfers: Consider scripting regular uploads or backups.
• Set Up a Web Server: If you’re hosting a website, configure Nginx or Apache to serve your uploaded files.
• Monitor Server Security: Regularly update your Droplet and monitor for unauthorized access.
